Unit features

` The actuator PSEN 2,1-20 belongs

to the safety switch

` 2 reed contacts (1 N/C, 1 N/O) ` Assured operating distance: 8 mm ` Assured release distance: 26 mm ` Square design ` Works magnetically ` Switching voltage 24 VDC ` Series connection via PSEN i1 in-

terface

` LED to display switch status

Unit description

The safety switch meets the requirements of EN 60204-1 and IEC 60204-

1. The safety switch only complies with EN 60947-5-3 in conjunction with the actuator PSEN 2,1-20 and its approved evaluation devices. The safety switch should only be connected to the evaluation devices listed under "Connections".

Function description

If the actuator is within the response range, the magnets switch the reed contacts on the safety switch. If the actuator is outside the response range (safety gate open), the reed contacts on the safety switch will switch.

Wiring

Please note:

` Information given in the “Technical

details” must be followed.

` Calculation of the max. cable runs

ance (see Technical details)

/ km = cable resistance/km

` When using evaluation devices with

delay-on de-energisation contacts, please note: –Delay time ≤ 30 s: Delay-on de-

energisation contacts satisfy the requirements of category 3 in accordance with EN 954-1 and the requirements of a PDF with single-fault tolerance (PDF-S).

–Delay time ≥ 30 s: Delay-on de-

energisation contacts satisfy the requirements of Category 1 in accordance with EN 954-1 and the requirements of a PDF with designed reliability (PDF-D).

` In the following commissioning cas-

es, check the function that detects shorts across contacts: – On evaluation devices with DC

supply voltage: Overall cable resistance ≥ 15 Ohms per channel

– On evaluation devices with AC

supply voltage: Overall cable resistance ≥ 25 Ohms per channel

– For details of how to perform the

test for shorts across the contacts, please refer to the operating manual for the relevant evaluation device.

Connections

NOTICE

The colour marking for the connection lead only applies for the cable that Pilz supplies as an accessory. The safety switch is shown in an unoperated condition.
